Maitiro ekushandisa Dry Ice Blasting Yakachena Surfaces？

Dry ice blasting inzira yekuputika inoshandisa yakaoma ice pellets semhepo inoputika. Iyo mukana wekushandisa yakaoma ice pellets sekuputika midhiya ndeyekuti haiburitse chero mabrasive particles ichiri kuita. Iyi mukana zvakare inoita kuti yakaoma ice blasting ive inonyanya kushanda yekuchenesa mhinduro.

Iyo abrasive inogadzira sei?

1.     Danho rekutanga: Iyo CO2 yemvura inoburitsa aizi yakaoma pasi pekukurumidza decompression. Ipapo ichamanikidzwa kuita mapellet madiki paminus 79 degrees.

2.     Munguva yekugadzirwa kweaizi yakaoma, mvura carbon dioxide inoyerera ichipinda mucylinder inotsikirira yepelletizer. Nekudonha kwekumanikidza mupelletizer, mvura kabhoni dhaikisaidhi inoshanduka kuita sinou yakaoma yechando.

3.     Ipapo sinou yakaoma yechando inotsikirirwa kuburikidza neextruder plate yoita mudonzvo wakaoma wechando.

4.     Nhanho yekupedzisira ndeyekupwanya matanda echando akaoma kuita mapellets.

Iyo yakaoma ice pellets inowanzoyerwa pa 3 mm muhupamhi. Panguva yekuputika, inogona kuputsika kuita zvidimbu zviduku.

Mushure mekunzwisisa kuti iyo yakaoma ice abrasive inogadzirwa sei, ngatizivei zvimwe nezve mashandisiro ayo kuchenesa nzvimbo.

Dry ice blasting ine matatu maitiro emuviri:

1.     Kinetic simba:Muchidzidzo fundoyetsimba , kinetic energy isimba rine chinhu kana chidimbu nekuda kwekufamba kwacho.

 Iyo yakaoma ice blasting nzira inoburitsawo kinetic simba kana yakaoma ice particle yarova painongedzopasi pekumanikidzwa kwakanyanya. Ipapo vamiririri vakasindimara vachaputswa. Iyo Mohs kuomarara kweakaoma ice pellets kwakangofanana nepurasita. Nokudaro, inogona kuchenesa nzvimbo yacho zvakanaka.

2.     Thermal energy:kupisa simba kunogonawo kunzi kupisa simba. Kupisa simba kunoenderana nekupisa. Muchidzidzo chefizikisi, simba rinobva mukupisa kwechinhu chinopisa isimba rekupisa.

Sezvambotaurwa, mvura co2 ichamanikidzwa kuita mapellet madiki paminus 79 degrees. Mukuita uku, thermal shock effect ichagadzirwa. Uye mumusoro wepamusoro wezvinhu zvinoda kubviswa zvicharatidza zvimwe zvakatsemuka. Kana pakange pave nekutsemuka kwakanaka muchikamu chepamusoro chezvinhu, pamusoro pacho pachava nebrittle uye nyore kuputsika.

3.     Nekuda kwemhedzisiro yekuvhundutsa kwekupisa, mamwe echando kabhoni dhaidhiodhiodhi anopinda mukati mepakatsemuka mune tsvina crusts uye sublimate ipapo. Iyo sublimates yechando kabhoni dioxide inoita kuti huwandu hwayo huwedzere nechikamu che 400. Iyo yakawedzera vhoriyamu yecarbon dioxide inogona kuputika idzi tsvina dzakasara.

Aya matatu maitiro emuviri anoita kuti yakaoma ice blasting ikwanise kubvisa pendi dzisingadiwe, oiri, girisi, masara esilicon, uye zvimwe zvirimo. Uye iyi ndiyo nzira yakaoma yechando kuputika kunochenesa pamusoro.
